511500 ÷ 2 
Our goal is to divide 511500 by 2.

Advancing to step 1:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 4 from 5 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Step 2:
2 goes into 11 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 10 from 11 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Going ahead to step 3:
When dividing 11 by 2, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 255.0
The remainder is 1 after subtracting 10 from 11.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Advancing to step 4:
When dividing 15 by 2, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 2557.0
Subtracting 14 from 15 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Moving on to step 5:
When dividing 10 by 2, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 25575.0
The remainder is 0 after subtracting 10 from 10.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Advancing to step 6:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 255750.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 255750.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 255750.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 255750.0 and a remainder of 0.0.
